Product Description:
GDSL-AIntelligent High Current Generatoris a high-performance current generating device designed by Guodian Xigao based on years of practical experience and in accordance with the latest national power industry standards, built upon the GDSL-A model. It combines the advantages of similar products at home and abroad, adopts numerical control technology, and has strong anti-interference capability. Compared with the previous generation of current generators, it features low power consumption, large capacity auto-transformer and a current transformer made of high-permeability iron core, resulting in high output power, small size, and light weight. It is mainly used for primary bus protection and complete transmission tests of various current transformers, as well as calibration of motor protectors, air switches, switchgear, circuit breakers, protection panels, etc.
Instrument Features:
-
320×240 LCD display, high-speed thermal printer. -
High-precision sensor and high-performance 14-bit AD acquisition chip. -
Human-machine dialogue full keyboard operation, intelligent whole process. -
Optional conventional current test, impulse instantaneous trip test, and transformer ratio polarity test, flexible and simple operation. -
Real-time display of output current and time results, intuitive display. -
Perfect overcurrent protection, arbitrary setting of target output current value, current upper limit, and current withstand time. -
Zero return detection function, test can only be carried out after zero return confirmation, safe and reliable. -
Approaching current rising algorithm, after reaching the set target output current, automatic current withstand timing starts, and the motor automatically returns to zero after timing ends. -
If the set output current upper limit is exceeded, the motor automatically returns to zero and an audible and visual alarm is triggered. -
Excellent software and hardware anti-interference design, multiple anti-interference methods, adapts to harsh electromagnetic environments. -
Automatic error diagnosis, easy to find and solve problems. -
Optional remote communication, door interlock alarm light and bell, open-circuit voltage calibration interface, etc.
